Do square business cards fit in a wallet?
Yes. Given that they are smaller than the typical 3.5-inch sized business card, square cards can fit nicely into a wallet. And not only that, square business cards fit inside a fob pocket (the small pocket in your jeans), or in a shirt pocket.
But don’t think that the smaller size means it is less memorable. As a matter of fact, square business cards tend to stand out more. For one, they have a different shape so they are more interesting to look at. Also, as they are smaller, they usually feature simple but vibrant designs.
